LETTER OR PAPER FILE.

$PEGIFICATION forming part of Letters Patent No. 295,391, dated March 18, 1884:; Application filed January 15, 1884. (No model.)

file. Fig. 2- is a front view of file with door open. Fig.3 is a crosssection showing wheelframe. Fig. 4 is a perspective view of one drawer in detail. Fig. 5 is the drawer (le tachcd from the file. Fig. 6 shows the file applied to a desk.

Referring more particularly to the drawings, it will be observed that the file consists of a suitable box or case, A, of any desiredsize. For ordinary office use a case thirtysix inches high, thirty-two inches long, and twenty inches wide is generally considered sufficient for the reception of current papers, letters, 850.; or the casing may be a part of a desk or table:

Inside of the case I place a vertical wheel revolving on journalsi. This wheelie made of two circular pieces of wood fastened to the two ends of the center block, 5. Near the outer edges of the disks are placed round pieces of wood 0, extending from one disk to the other, with the ends fastened to the two disks. A spring, f, is secured to each stick or round 0. These springsare preferably made of brass wire of suitable size, the ends being secured to the pieces 0, so that when the spring is raised, by pushing in the tray B it will not slip on the piece a. Each tray B, of which there may be any suitable number, is preferably made of wood; but tin or paper may be used. A. flap, h, of heavy paper or other suitable material, is glued or secured to the back edge of the bottom a. The sides of the wheel, or its inner faces, have supportingledges or bracket-pieces d, the exterior edges of which have the shoulders or stops (2. The trays or drawers rest upon these supports (1.

In operation, the papers, letters, &c., are laid on the bottom it of the trays. The flaps 71. are then folded over them, and the tray slipped intoposition on the supports (I, as shown in Fig. 4, the front h of the drawer resting against the shoulder c. This .pre-

rents the tray slipping out or falling when the wheel is revolved. Before the trays are preferably have twenty eight trays in thewheel, one for each letter of the alphabet one for miscellaneous papers, one for bills, re-

ceipts, &c.

The trays are lettered on the end next the hinged door m, and there may be corresponding letters on the disks. The trays are re moved by raising them so as to clear stop e, and then sliding them out.

It is not necessary that the trayrcceptacle be circular, as it may be square or rectangular, there being left sufficient space between the sides of the case for it to revolve in the bearings z.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

I. In a paper and letter file, the combination, with a vertically-revolving wheel entirely inclosed within a frame, A, of the trays B, provided with the flaps h, which are held in position by the springs f, secured to the connectingrods 0, the said rods being secured to each of the tray-supports (I, having a shoulder, 6, against which each of the trays abuts, substantially as and for the purpose set forth.

2. In a paper and letter file, the frame A, adapted to inclose a vertically-revolving wheel provided with a series of trays, B, arranged in guides formed by the supports d, having the shoulders e, in combination with the connecting-pieces 0, provided with the springs f, and a flap secured to the tray B, substantially as andfor the purpose set forth.

3. In a paper and letter file, a verticallyrevolving wheel or tray receptacle provided on its inner faces with a series of tray-supports, (I, having shoulders e, as and for the purpose set forth.
